Regardless of agreeing with the advice, a 41yo giving advice on surviving the 40s seems a bit arrogant. Being 41 is different from 46 which is different from 49, and he just doesn't know yet. The right title should be "how I feel after a year in my 40s".
It's his strategy going forward. He isn't saying he completed his 40s at the age of 41. You would prefer he share his strategy for 40s at 50? Seems pedantic.
